posite sides of thel ridge and positioned .on the middle lines of the pairs of oppositely disposed roof sheets.

Bettens 22 are arranged between the side flanges of the spaced roof sheets, the width of the battens being slightly less than the width of the spaces between adjacent roof sheets. These battens may be nailed or otherwise secured to the roof sheathing, or they may be left loose thereon and secured by the saine means vwhich secures the roof sheets and side seam covers 23 which straddle them. The side seam covers are inverted channel shape, with their side walls 24 hooked undei the inner'edges 17 of the side flanges of the roof sheets, as shown in Fig. 3. The ridge ends ofthe side seam covers have upturned flanges 2G across their Vtop walls and the eaves ends have projecting tops 27 which are adapted-to be bent down over the eaves of the car to' cover the ends of the battons and spaces between their side walls.'

Thel eaves ends of the roof sheets and side sea-n1 covers are loosely held down upoir the substructure by means ot' angle flashing (See Figs. l e

strips Q8, and angle clips 29. and 2.) The angle flashingstrips 2S are arranged lengthwise of the car along the eaves below7 the ends of the rootI sheets. and passing-underneath the battens and side seam covers. rfhe inner margins 30 ot' the flashing strips are folded back over the intermediate portions, and the eaves ends 3l ot' the roof sheets are turned under and ffhooked into the turned over inner margins of the flashingstrips to form a flexible joint. The outer margins of the flashing strips are bent down over the side of' the car, and are fas- 'lhe angle clips QS) are outside of the flashing` strips, and are bolted to the side of the car below the eaves. 'lhe angle, clips are spaced away from the ends of the. roof' sheets and side seam covers and have bent bortions projecting over the eaves and overlying the root' sheets or side seam covers. 'lhe angle clips prevent the roof sheets and side seam covers from lifting'ofi" the substructure, but do not clamp them rigidly in fixed position. The vroof sheets are provided with bosses 2&5 at [he middle points of their ridge ends inside of: the ridge flaliges aud these bosscsli register with the bosses (3l of theI ridge sfrip and position the 'loof sheets at their ridge, ends. lunning board saddles -fvare arranged across the ridge on the middle lines of the sheets, with their un` densides shaped to conform to the ridge peak of, the roof and provided at their ends with recesses 37 for the roofl sheet bosses. '.lhe'running board saddles f straddle the ridge seam covers and are fastened to the substructure by vertical bolts 3S, which pass through holes in the scam covers and ridge strips. 'l`he scam covers and ridge strips are i and l2 for the ruiming board saddles,

flanged up around the holes for the running board saddle bolts 3S to keep water from following the bolts into the car. The recesses in the ruiming board saddles for the root` sheet bosses and the grooves for the Aridge seam covers, are wider than the parts holes which are threaded to 'fit vertical bolts @f2 which secure them to the substructure.

Running board saddles l-l are ar 'anged over the side seam covers, resting on them and heilig supported by the battens. The running board saddles ll are recessed for the corner caps, and the securing bolts 42 for the corneil caps go through the running board saddles and hold them down. Running boards l5 vextending lengthwise ofthe car, are supported on the running board saddles and are nailed or otherwise securely. fastened thereto. The ridge strips are provided with flangcd holes for th'e bolts 38 the the the flanges projecting up -closely around boltsto prevent water from following bolts into the car.

` From the foregoing description it is evident that the root' sheets are free to move upon the car substructure in response to distortions thereof, but arev positively l0- aited in proper position and held from slipping ofil the eaves by the bosses and Saddles. The ridge strips are fixed in position by bolts`r and maintain the central alinemnt of the roof sheets.. The ridge and side seam covers permit movement of the roof sheets, and the forni ofthe interlock between thcni prevents 'atei' from entering the car through the seams. The ridge strips catch any water which may get through the ridge caps or between them and the roof sheets, and deflect this 'ater away from tlvl ridge of' the air. rThe amount ofwater which will reach the ridge. strip`is small, and there is little chanceot its going through the tongucd and grooved sheathing boards belowthe edges of' the ridge strip and into the car at any other point than at the ridge.

'lhe invention is not restricted to the precise forms and arrangements of the parts as shown and described. i

What I claim as my invention is as follows: v
